http://en.wikipedia.org/wiki/Walking_ghost_phase “The walking ghost phase of radiation poisoning is a period of apparent health, lasting for hours or days, following a dose of 50 sieverts of radiation. As its name would suggest, the walking ghost phase is followed by certain death.” This condition is mentioned as a potential disadvantage of the neutron bomb—troops surving the initial explosion, and in this phase “would likely be aware of their inevitable fate and react accordingly.” 14:00
